'cononn'm oonsmt'oc'rzon To cZl whom tt rnay concern: Be it known that LsAtiiERr A PAULir, a citizenof the United States of: America; residing at'Youngs town, iii-the county of Mahoning and State of Ohio,

5.- have'invented certain newand usefullmprovements inConcreteConstructions, of which-the following is a specification, reference heing compal ly'ing drawings. v

had therein to the acvention relatesto certainnew and useful im- 10 fproi reinnts in concrete construction, and the-invenno; r ates more particularly to a 'novel form of wall crete together. I v

:The primary object of the invention is the provision employed for lockiri'gftwo walls or sections of con novelmeans for locking twos ectio'ns of eoncretetm bleQ v Another-important object of the invention is the provision of novel means for locking twodistinct and gether whereby'lateraldisplacement will. be impossiseparate walls or portions of concrete together. To

this end, I have devised a novel 'nieans for interlocking the portions of concrete wall together, said means consisting of providing one section ofconcretewith lugs adapted to fit in suitablerecesses formed in an-.

other portion of the concrete.

in connection with theinterlocking feature of my improved concrete 'constructirm, i employ a wall tie consisting-of a metallic rod or wire bent to engage the lugs ofva concrete portion, said ties being impinged between thefconcrete portions when they are constructed. n v

' In order thatwall ties may he practical and be used it is neccssary'that an inexpensive construction be employed, which will' be strong and durable, conse quently, l have constructed my improved interlocking feature for concrete constructions upon simple lines which will permit of its extensive use.

,The above construction will he hereinafter more rihed and then specifically pointed out in and referring-to the drawing accompanynate corresponding parts throughout the several views, in which'. a n Figure 1 is a vertical sectional view of a concrete 4 construction, illustrating the interlocking feature of my invention, Fig. 2 is a top plan view of aportion of the same, and Figs. 3 and 4 are detail views of wall ties,

the construction of the same representing a modii'ication.

In the accompanyingdrawing, l have illustrated a portion of. aconcrete construction comprising two walls 1 and 2, said walls being-formed of sections of concrete 3, 4, 5 and 6. The sections of concrete?) and 5, whi ch rest upon the sections 4 and 6, are provided with recessesfi, 7 adapted to receive lugs 8, 8 formed,

and vlugs are preferably iol-med centrally of the concrete portions, and when the concrete portions are of considerable length, plurality of lugs andrecesses .rnay' be used to fix one concrete portion in engagementwith its adjoining portion, whereby one cannot bc come laterally displaced independent oi the other.

Prior to placing the concrete portions and 5 upon the portions 4 undo, I. employ wall ties 9 for locking thewallfgl in engagement with the wall 2. The preerred form of wall tie is illustrated in lhgs. l and 2 oi thodniwing, said tie simply consisting of a piece of wire or metallic rod bent to conform substantially to the shape of a. figure (sight, the loop ends 10, 1O of th e tie engaging over the lugs 8, 8 oi the concreteconstruc- Lions 4 and o, and when. the concrete portions fl and 5 are constructed upon the portions 4 and (S, the ends of the tiewill be locked Within'the concrete construction and it will be impossible for one end ol'the tie to move iedepemlently ol theother, especially when the ties are given sufficient rigidity, such asacquired by constructing the ties of metal.

Patented Sept. 3, 1907.

In Figs; 3 and 4 of the drawing, Ihave illustrated modified forms of ties, the tie ll being formed of a single strand of wire or a rod upon the ends of which are formed eyelets l2, 12, adapted to engage over thelugs 5i, 8 of the concrete 'constru :tion.- In Figs. 4 of the drawing, 1 have illustrated-a tie 14 which has ends substantially linkshaped, which serve functionally the same purpo'seas the ends or the ties heretofore descrihed. v t

It will be apparent from the foregoing description that 'I have devised a novel interlocking connection; for sections cit-concrete and I do not care to confine the useoi my. improved wall tie specifically to concrete constructions, asterra ootta bricks andjhlocks may be readily obnstrurtedwith lugs and recessesf in engagernent'with which ,my improved ,W'all tiecan be placed. i I

. It will be noted't-hat various changes may be made in thedetails of constlructionwithout departing'from the general spirit and scope of the invention.

What I claim and desire to secure by Letters Patent, is:'-

,A concretehuildlng constrnctlon consisting oftwo parallel walls each composed-of concrete hlocks' each hlock having. an integral projection'pn one-sidesnd a recess on the other side extending tromone nae" facing inwardly and n with the shles'converging towrii'ds the face of the block and with a Gepressioxr-ln thel'nner larger and of'the recess to receive the projection of the adjacent hloek,-und

metallic Lle memhers substantially. figure -8 shaped and engaging the projections-and'eorresponding. to -and .en. gaging the sides of flier enemies i V In testimony whereof I; aflix my signature in the pres- ALnEs'nA, PAULYJ. Witnesses I Kremlin Gnomes,- Tl hil Resumes.
